A CORPORATION OF NEVT JERSEY.

ROUNDING- AND CHANNELING MACHINE.

Application filed September 25, 1916.

To all whom it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Rounding and Channeling Machines; and I'do hereby declare the following to be a full, clear, and

- exact description of the invention, such as form depth throughout and at a greater distance from the edge of the sole through the shank than about the forepart, the edge of the sole being trimmed or chamfered off up to the edge of the channel flap in finishing the shoe after the outsole has been sewed thereto. In doing certain classes of work the trimming or chamfering of the edge of the sole required along the shank is objectionable. For instance, in making shoes with thin edge shanks in which the sole edge is reduced in thickness by skiving the outsole outside the root or bottom of the channel through the shank, the subsequent trimming of the sole edge tends to nullify the effect of the skiving.

It is the primary object of the present invention to so channel the sole that comparatively little cutting away or trin'iming of the sole edge through the shank will be required in finishing the shoe. To this end one feature of the invention contemplates the provision of means for cutting a channel having its outer edge and the edge of the channel. flap a uniform distance from the soleedge and having'its root or bottom a greater distance from the sole edge through the shank than around the forepart.

This manner of cutting the channel provides a wide channel flap'in the shank which extends nearly to the edge of the sole so that little trimming is required in finishing the sole edge afterthc channel iiap has been Specification of Letters Patent.

laid. This is specially desirable in the case of skived shanks, since the broad channel flap will be of suflicient Width to properly cover the outseam, and the slight trimming required will not materially increase the thickness of the skived edge in the finished shoe.

Any suitable means may be emploved to cut the channel as above indicated, although it is preferred to utilize a channel knife of the usual construction so mounted that it will cut a channel at a uniform distance from the sole margin, and an auxiliary knife for increasing the depth of the channel and width of the channel flap through the shank. In case a thin edge shank is to be formed it is also preferred to utilize the auxiliary knife to skive the sole edge through the shank as well as to increase the depth of the channel and width of the channel flap. The skivingmay, however, be done as a separate and subsequent operation, if desired. The auxiliary knife may also be utilized not only to increase the depth of the channel through the shank but may also be utilized to skive the edge of the sole about the forepart as well as through the shank.

The invention also includes certain further features of construction and combinations of parts hereinafter described and referred to in the claims, the advantages of which will be apparent to those skilled in the art from an inspection of the accompanying drawings and the following de-.

tailed description of the mechanism illustrated therein.

In the drawings, Figure 1 is a partial side elevation of a rounding and channeling machine showing the application of a preferred form of the present invention thereto; F 9 is an enlarged detail in side elevation of the channeling knives and their appurtenant parts. showing the auxiliary knife in active position; Fig. 3 is a front elevation of the parts shown in Fig. 2; Fig. L is a view similar to Fig. 2 (with certain parts broken away to show internal construction), with the auxiliary knife in inactive position; 5 is a section taken on the line 55 of Fig. 2; Fig. 6 is a detail representing the relative cutting actions of the two knives: and Fig. 7 is a View of a rough-rounded and channeled sole, 1llnstrat-' ing the action of the knives of the present invention thereon.

. The invention is shown in the drawings as embodied in a rounding and channeling machine which, in its main features, is substantially like the rounding and channeling machine shown and described in Letters Patent No. 1,030,606, dated January th, 1912. The machine is provided with a trimming knife 10, a channel-forming knife 12, a feed jaw 14, a crease guide 16, and a forepart guide 18 which is movable into and out of operative position by mechanism substantially as described in said patent. The channeling knife '12 differs in its mounting and mode of operation from the channeling knifeshown and described in said patent, in that it does not move vertically to vary the distance of the channel from the margin of the sole. As is customary in the operation of rounding and channeling machines, the

I crease guide 16 engages the shoe during the cutting of the channel in the shank of the shoe, and upon the completion thereof, the forepart gulde 18 is moved into operatlve position in engagement with the shoe. The

- operator throws the forepart guide 18 into operation by movement of a treadle rod 20. In addition to the channel knife 12 the machine is provided with a cooperative auxiliary knife 22 for increasing the depth of 3 the channel through the shank. As shown,

this knife is also constructed and operated.

to skive the edge of the sole through the shank. The auxiliary knife is normally in active position, as shown in Figs. 1 and 2, and is moved out of active position in passing fro-m the shank to the forepart, and is again moved into active position in passing from the forepart to the shank.

When the operator manipulates the treadle, he thereby depresses the rod 20, which throws the forepart guide into operative position as described in said patent. This movement rocks a bell crank, lever 24, pivoted at 26 in the frame of the machine.

As the bell crank lever 24 is oscillated, a pin 28, fixed in the outer end of an arm 30' of the lever, is caused to travel in a slot 32 in a lever 34 which is pivoted at 36 in the machine frame. When the pin 28 reaches the innerend 38 of the slot 32, it swings the lever 34 and thereby rocks a bell crank lever 40 which is pivoted at 42, and is connected with the lever 34 by a link 44. The end of the link may beadjustably secured in a slot p 46 in the lever 34 to regulate the movement ofthe bell crank lever 40 and thereby control, through the connections between the lever and the auxiliary knife 22,'the movement imparted to the latter. The bell crank 40is connected by a link 48 with a shaft. 50 in such manner as to impart oscillations thereto. 50is fixed an arm 52, pivoted on the outer On the forward end of the shaft struction and mode of operation of the shaft is substantially like the correspondingly situated shaft shown and described in said patent. The yoke carries the auxiliary knife 22 which is pivotally mounted thereon so that it may be given forward and backward as well as a vertical movement by the vertical movement of the yoke. Pivoted at 70 on the yoke 60 is a bifurcated oscillatory auxiliary knife support 72. Secured to the auxiliary knife support by a screw 74 is an adjustable knife carrier 76, the split upper end 7 8 of which is elongated to form a bearing clamp 80, in which is held the shank 82 of the auxiliary knife 22. A screw 84 The knife proper cooperative relation between the.

knife edges. The means for advancing and retracting the auxiliary knife as it is moved vertically comprises a cam block 90 adjustably secured to the support 63v by a screw 92. A guide pin 93 holds the cam block from turning in case it is necessary to adjust it vertically. The cam block is provided with two cam grooves; 94 situated on opposite sidesof the block, which are adapted to be engaged by cam rolls 96carricd by the auxiliary knife support .72. The cani grooves 94 are of such shape that when the shaft 50 is oscillated. to cause the link 51', and consequently the support 72 to rise the auxiliary knife 22 is moved upwardly and backwardly into a position clear of the shoe 65 whichisformed or secured on the support 63 and acts as a sole support adjacent to the point .of operation of the knives. supplemental sole support 98 is adjustably secured to the yoke 60 below the block65.

During the sole channeling operation the v channeling. knife 12. is. in constant'engagement with the sole, and consequentlycuts therein a channel, the outer edge of which is at a uniform distance from the margin of the sole. The auxiliary knife is located a little to one side of the channeling knife, as shown in Fig. 3, and its cutting edge is dlsposed at such an angle that it intersects the plane of the cutting edge of the channeling knife at its lower point. The cutting edge of the auxiliary knife extends below the lower point of the channeling knife and above the upper point of the channeling knife. It is seen, therefore, that while the auxiliary knife is in active position, it will deepen the channel formed by the channel ing knife, and simultaneously therewith the upper part of its cutting edge will bevel the margin of the shank. The relation of the cutting edges of the two knives is indicated in Fig. 6.

During the operation through the shank the auxiliary knife remains in active position as indicated in Figs. 1, 2 and 3, and acts to deepen the channel out by the channel knife 12, and also to skive the edge of the sole beneath the channel flap, as indicated in Fig. 6. When the ball line is reached, the forepart guide is moved into active position by depressing the treadle rod 20, and through the connections described the auxiliary knife 22 is raised and swung back out of active position, as indicated in Fig. 4. During the operation around the forepart, or from the point indicated at 100 to the point indicated at 102, in Fig. 7 the auxiliary knife remains out of active position and a comparatively shallow channel is cut by the knife 12. When the point 102 is reached, the forepart guide 20 through the connections described, moves the auxiliary knife forward and down into active position so that it acts to deepen the channel and skive the edge of the sole during the remainder of the operation through the shank.
